Small quake south of Page, Arizona

There was a magnitude 2.8 earthquake south-southwest of Page, Arizona, on Saturday morning, April 6, about 8:35 a.m. local time.

We notice that the epicenter is generally near the Bitter Springs landslide that closed US 89 and wondered if it might be related to activities to re-open the road.

Our friends at the University of Utah Seismograph Stations located the event with an extended number of phases, indicating a focal depth of 10 km.  So, for now, we are treating it as a real seismic event.

Thanks to Jeri Young for providing the additional insights.
